On the occasion of the 70th birthday of Czech President Vaclav Klaus, a number oi distinguished people have paid tribute to his staunch and lucid contribution to internatioinal affiars. Among them is Professor David Henderson, former head of Economics and Statistics Department of the OECD in Paris, currently a Fellow of the Institute of Economic Affairs in London, and chairman of the Academic Advisory Council of the Global Warming Policy Foundation, who writes of Klaus's views on "global warming": "I believe that in his lonely role, as outspoken critic and protester, Klaus has by no means overstated the grounds for concern about the situation of today. From the outset, the treatment of climate change issues by governments has gone badly astray. Both the content of policy and its underlying rationale give grounds for serious concern."
